Isn't the ozon layer keeping in the heat as well as filtering out harmful rays? Or is it cooling down the earth as well?

Reply to Large parts of Europe are warming twice as fast as the planet on average. As a consequence of human emissions of greenhouse gases, the climate across the continent has also become drier, particularly in southern Europe, leading to worse heat waves and an increased risk of fires. by MistWeaver80
"Yes, well. With these heating prices, it better..."
I'm sorry.

Reply to comment by Kennyvee98 in Alzheimer's disease can be diagnosed before symptoms emerge by BlitzOrion
“When both beta-amyloid and tau are present in the brain, it can no longer be considered a risk factor, but rather a diagnosis. A pathologist who examines samples from a brain like this, would immediately diagnose the patient with Alzheimer's”, says Rik Ossenkoppele, who is the first author of the study and is a senior researcher at Lund University and Amsterdam University Medical Center.
He explains that Alzheimer’s researchers belong to two schools of thought – on one hand, those who believe that Alzheimer's disease cannot be diagnosed until cognitive impairment begins. There is also the group that he himself and his colleagues belong to – who say that a diagnosis can be based purely on biology and what you can see in the brain.
“You can, for example, compare our results to prostate cancer. If you perform a biopsy and find cancer cells, the diagnosis will be cancer, even if the person in question has not yet developed symptoms”, says Rik Ossenkoppele.
Recently, positive results have emerged in clinical trials of a new drug against Alzheimer's, Lecanemab, which has been evaluated in Alzheimer's patients. Based on this, the study from Lund University is particularly interesting, say the researchers:
“If we can diagnose the disease before cognitive challenges appear, we may eventually be able to use the drug to slow down the disease at a very early stage. In combination with physical activity and good nutrition, one would then have a greater chance of preventing or slowing future cognitive impairment. However, more research is needed before treatment can be recommended for people who have not yet developed memory loss”, concludes Oskar Hansson.

It has long been known that there are two proteins linked to Alzheimer’s – beta-amyloid, which forms plaques in the brain, and tau, which at a later stage accumulates inside brain cells. Elevated levels of these proteins in combination with cognitive impairment have previously formed the basis for diagnosing Alzheimer's.
“Changes occur in the brain between ten and twenty years before the patient experiences any clear symptoms, and it is only when tau begins to spread that the nerve cells die and the person in question experiences the first cognitive problems. This is why Alzheimer's is so difficult to diagnose in its early stages”, explains Oskar Hansson, senior physician in neurology at Skåne University Hospital and professor at Lund University.
He has now led a large international research study that was carried out with 1,325 participants from Sweden, the US, the Netherlands and Australia. The participants did not have any cognitive impairment at the beginning of the study. By using PET scans, the presence of tau and amyloid in the participants' brains could be visualized. The people in whom the two proteins were discovered were found to be at a 20-40 times higher risk of developing the disease at follow-up a few years later, compared to the participants who had no biological changes.

Reply to Wear and tear from lifelong stress can increase cancer mortality. Even without adjusting for any potential confounders like age, social demographics like race and sex, those with a high allostatic load were 2.4 times more likely to die from cancer than those with low allostatic loads by Wagamaga
How do you measure allostatic load? Is anxiety allostatic buildup?
